dynamically changing where an action forwards to.

[peter cooke]

I have devleoped a web app using action forms, company loves the app.
However the buisess rules have changed.

If the action succeeds, the company now wants to forward to some URL that they want to specify as a paramter in the request, or a database table lookup.

any suggestions

Hi,

I just wonder whether the URLs you want to forward after action succeeds are limited or going to change dynamically.

[peter cooke]

Yes they want to randomly change where the success of an action goes. They want to be able to speciy either a relaitive URL or to some URL on another webserver/web app server.

I don't know why, but that is what they want.

Hi Peter,

It is pretty easy to re-direct an Action dynamically. Remember, your ActionMapping class passed into the execute() holds instances of an ActionForward object. Each ActionForward represents a different forward you can redirect to. You normally use the ActionMapping.findForward() method to return an ActionForward.

You can create an ActionForward directly and return it from the execute method. You can look at the source for the ActionForward. There are a number of different public constructor you can use to set what you are looking for.

I hope that answers your question.

Thanks,
John

I think John has got the right answer for you.

So, to solve this problem
1. Change code in ActionForm or not
2. Change config in struts-config.xml or not
